The key is not so much which tires but how deep is the snow. I've tried every tire I could get to fit my banshee and there really wasn't ALOT of difference ebtween them. The problem is getting stuck from the rear skid getting high centered. The Bear Claws I tried probably did the best but the disadvantage over using a taller heavily lugged tire is the weight of the tire. It really kills the low end and you really need that to get started. If you spin and the snow isn't already packed from sled traffic, you'll be lifting the back out of another rut. Once you get moving, it's great. The starts are the problem. You could use paddles if the snow is deep enough to keep the paddles from hitting the frozen ground. Other than that, use what you've got.
